A Ka/IF down-converter for space application with embedded microwave passives and DC networks

This paper presents the electrical design and measurements of a Ka/IF down-converter module for multimedia space application. Using the partitioning approach and MCM-D technology, a collective process, both microwave and DC passives were embedded on the substrate. A size reduction by a factor 2 of the module is finally obtained in comparison with current qualified technologies with no degradation of the electrical characteristics.
